Die Erfindung betrifft eine Vakuumampulle zur sterilen Entnahme von Blut und anderen Flüssigkeiten mit einem den Ampullenraum abschließenden aus Gummi oder Kunststoff bestehenden Hohlstopfen, der eine Kanüle trägt, die am unteren Ende in ein Röhrchen endet, das umgebogen ist und zwecks Abdichtung gegen das untere Ende des Hohlstopfens drückt.The invention relates to a vacuum ampoule for the sterile withdrawal of blood and other liquids with a hollow stopper made of rubber or plastic that closes off the ampoule space, who carries a cannula that ends at the lower end in a tube that is bent over and for the purpose of sealing presses against the lower end of the hollow plug.

Eine solche bekannte Vakuumampulle ist in Fig. 1 dargestellt. Sie besteht aus einem Glasbehälter (1), welcher mit einem Gummistopfen (2) verschlossen ist. Durch den Gummistopfen ragt ein Glasröhrchen (3), das innen eine eingeschmolzene Kanüle (4) enthält. Das Glasröhrchen ist am unteren Ende umgebogen und drückt mit seiner unteren Öffnung gegen das Innere des Stopfens. Der Glasbehälter (1) ist luftleer gepumpt. Wenn man das Glasröhrchen (3) mit einer Ampullenfeile abschneidet, so kann man nach Einführen der Kanülenspitze in eine Ader durch entsprechendes Abdrücken des Kanülenendes vom abgedichteten Gummi bewirken, daß das Blut unter sterilen Bedingungen in die Ampulle eingesaugt wird.Such a known vacuum ampoule is shown in FIG. It consists of a glass container (1), which is closed with a rubber stopper (2). A glass tube (3) protrudes through the rubber stopper, which contains a fused cannula (4) inside. The glass tube is bent at the lower end and presses with its lower opening against the inside of the stopper. The glass container (1) is evacuated pumped. If you cut off the glass tube (3) with an ampoule file, you can insert it of the cannula tip into a vein by pushing the cannula end off the sealed Gums cause the blood to be sucked into the ampoule under sterile conditions.

Der Nachteil dieser Konstruktion besteht darin, daß sich der Stopfen nur sehr schwer in die Ampulle einführen läßt. Außerdem bleibt das Vakuum in der Ampulle oft nicht genügend lange bestehen.The disadvantage of this construction is that the stopper is very difficult to get into the ampoule can introduce. In addition, the vacuum in the ampoule often does not last long enough.

Diese Schwierigkeiten werden gemäß der Erfindung dadurch behoben, daß in an sich bekannter Weise der oben verschlossene Ampullenhals über den die Kanüle (4) tragenden und vom unteren zum oberen Ende des Ampullenraumes hineingepreßten Stopfen (2) und die Kanüle (4) gezogen ist und daß der Ampullenkörper am unteren Ende unter Hochvakuum abgeschmolzen ist.These difficulties are eliminated according to the invention in that in a known manner the The neck of the ampoule closed at the top over the one carrying the cannula (4) and from the lower to the upper End of the ampoule space pressed plug (2) and the cannula (4) is pulled and that the Ampoule body is melted at the lower end under high vacuum.

Ampullen, bei denen der oben verschlossene Ampullenhals über den vom unteren zum oberen Ende des Ampullenraumes eingepreßten Stopfen und darin befestigte Kanüle gezogen ist, sind an sich nur für Injektionszwecke bekannt, wobei der Ampullenraum mit dem Injektionsmittel gefüllt ist und dieses von unten her aus dem Ampullenraum verdrängt wird. Dementsprechend fehlt bei diesen Ampullen auch das an sich bekannte aus einem gekrümmten Röhrchen bestehende Ventil im Stopfen.Ampoules in which the neck of the ampoule closed at the top extends from the lower to the upper end of the ampoule chamber pressed-in stopper and cannula attached therein are in themselves only for Injection purposes known, wherein the ampoule space is filled with the injection agent and this from is displaced below from the ampoule space. Accordingly, this is also missing from these ampoules known per se consisting of a curved tube valve in the stopper.

Die Herstellung der erfindungsgemäßen Vakuumampulle kann in der Weise geschehen, daß man zunächst einen Glaskörper gemäß Fig. 2 herstellt. In diesen Glaskörper preßt man gemäß Fig. 3 einen Hohlstopfen (Fig. 4 a und 4 b), und man schmilzt hierauf das hintere Ende unter Hochvakuum zu. Der Hohlstopfen trägt in an sich bekannter Weise eine Kanüle, die gemäß Fig. 4 a, Ziffer 5 am unteren Ende Vakuumampullen zur Entnahme von Blut und anderen FlüssigkeitenThe production of the vacuum ampoule according to the invention can be done in such a way that one first a glass body according to FIG. 2 produces. In this glass body is pressed according to FIG. 3 a Hollow stopper (Fig. 4 a and 4 b), and the rear end is then melted under high vacuum. Of the Hollow stopper carries a cannula in a manner known per se, which according to FIG. 4 a, number 5 at the lower end Vacuum ampoules for taking blood and other liquids
